Carbon-rich molecules were detected in samples collected from Enceladus’ ocean—yet another indicator that it could host microbial life. Continue reading Evidence of Organic Molecules Found in Plumes Ejected From Saturn’s Moon
Citizen scientist extraordinaire [Thought Emporium] put out a new video about colorful quantum dots which can be seen below the break. Quantum dots are a few nanometers wide and you can tell which size they are by which color they fluoresce. Their optical and electrical properties vary proportionally with size so red will behave differently than purple but we doubt they will taste like “cherry” and “grape.” Let’s not find out. This makes sense when you realize that a diamond will turn into black powder if you pulverize it. Carbon is funny like that.
[Thought Emporium] uses the video for …read more
When a rainforest is clearcut for agricultural use, we only see the surface problems: fewer trees, destruction of plant and animal habitats, and countless other negative effects on the environment. A lurking problem, however, is that the soil is often non-ideal for farming. When the soil is exhausted, the farmers move further into the rainforest and repeat the process.
In the Amazon, however, there are pockets of man-made soil that are incredibly nutrient-dense. Figuring out how to make this soil, known as Terra Preta, on a massive scale would limit the amount of forest destruction by providing farmers a soil …read more
Many credit the invention of the incandescent light bulb with Edison or Swan but its development actually took place over two centuries and by the time Edison and Swan got involved, the tech was down to the details. Those details, however, meant the difference between a laboratory curiosity that lasted minutes before burning out, and something that could be sold to consumers and last for months. Here then is the story of how the incandescent light bulb was invented.
Our story starts in 1761 with Ebenezer Kinnersley. In a letter to Benjamin Franklin he described experiments he …read more

Additive manufacturing startup Carbon is on a mission to help manufacturers and designers cut their costs, waste less energy and materials while speeding up the time it takes to get from concept to product on the market. The company, which has raised $221 million in venture capital, is firing up a new service aimed at contract manufacturers, and other high volume manufacturing businesses,… Read More Continue reading Carbon moves into high-volume manufacturing with SpeedCell system, and bigger 3D printers

Researchers have injected carbon dioxide into basalt and turned it into solid rock in two years. This effort offers a potential solution for curbing the high carbon gas emissions in our atmosphere. Continue reading Scientists Turned Carbon Dioxide Into Solid Rock In 2 Years
Stronger plants could make for a carbon sequestration strategy within reach of everyone. Continue reading More Powerful Enzymes Could Help Plants Save the World from Climate Change
Resistor: A passive chunk of material that resists the flow of electrical current. A terminal is connected to each end you’re done. What could be simpler?
It turns out it’s not so simple at all. Temperature, capacitance, inductance and other factors all play a part in making the resistor a rather complex component after all. Even its uses in circuits are many, but here we’ll just focus on the different types of fixed-value resistors, how they’re made, and what makes them desirable for different applications.
Let’s start with a simple one, and one of the oldest.
These are …read more
